Three winners and one special mention have been announced for the 2018 Prix du Livre at Rencontres d’Arles – and in all four cases, the books use archival or found photography. The Author Book Award went to Laurence Aëgerter’s Photographic Treatment, which is published by Dewi Lewis; the Historical book award went to The Pigeon Photographer, a collection of images by Julius Neubronner published by Rorhof; and – controversially – the Photo-text Book Award went to Adam Broomberg and Oliver Chanarin’s War Primer 2, which was first published by MACK in 2011 but reissued in paperback this year. A special mention went to Giorgio Di Noto’s The Iceberg in the Author Book Award, which is published by Édition Patrick Frey.
